Yes man.... That's a bad story actually. You are going to install all the apps manually and adjust all your settings manually as well. If you don't have a lot of apps and files it's ok, if not, then find a time and do it. Actually the only way to over come that password lost is to restore the iOS, after restoring the iOS if, you restore your backup, then that password for restriction will be back again, so that actually all your backups are of no use since they have your settings information. Got to do it all manually now. Good luck to you.
